1 ARGAND CANDLE.

SPECIFICATION forming part of Letters Patent No. 284,486, dated September 4, 1883.

' Application filed April 27, 15582. (No model.)

To all whom it may concern;

Be it known that we, J OHN B. RODMAN and J UDSON D. BINGHAM, of Fort Leavenworth, in the State of Kansas, have invented a new and usefullmprovement inArg'and Candles 5 and we declare the following to be a full, clear, and exact description of the same, such as will en able others skilled in the art to which it per tains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

, Our invention relates to a candle made upon the Argand principle, wherein a supply of air can be fed from within to the center of the flame, as will be hereinafter more fully set fOIbhfZL-Hd specified in the claim.

Heretofore in the manufacture of candles they have been made with acentral wick, about which tallow, stearine, paraffine, or other material is molded. So, also, the candle has been" made with a central orifice, through which the wick is subsequently drawn, or with a central orifice, through which a wick-tube for contain ing a wick may be inserted.

Our invention consists in a tubular candle provided with a tubular wick,.in combination I with means for supporting the same and permitting the passage of a current of airfrom its base to its top, as hereinafter particularly described, and then specificallypointedout in the claim. r

In the drawings, Figurel is a View in elevation; Fig. -2, a longitudinal central section;

I Fig. 3, a cross-section of a candle embodying our invention. Fig. 4 represents the device as applied to acar-lamp. Fig. 5 represents variations ofthe invention. i

In carrying out our invention, A represents atubular wick.

B is the tallow or other material which forms the body of the candle.

In manufacturing candles of this character the tubular wick may be suspended within the i of the tube; but we prefer, generally, to slip candle-"mold andthe material poured in about the wick, in the usual manner, and be permitted to cool. I

I The material of which the wick is composed may be sufficiently impervious to prevent the liquid tallow or other material from passing through its meshes, and thus fill up the interior a suitable mandrel into the tubular wick and retain the mandrel within the wick until the tallow shall have set, after which the mandrel can be withdrawn, and the tubular space is thus left free and open. 7

' We would alsohave it understood that we propose to make these candles, usually, with a single tubular wick of greater or less diame ter, but do not limit ourselves solely to a single wick, for we may locate side by sidetwo or more similar tubular wicks in the same-candle for special purposes where a stronger light is required. A candle of this character, in order to work upon the Argand principle, is used with a candlestick permitting the admission of air at its base, so that the air may passthrough the candle from its base to its top. So, also, we pro= pose in some instances to employ a lamp-chimney surrounding the top of the candle, the entire quantity of air necessary for combustion being permitted to pass in through the tubular wick, or a part of the air entering through the wick, and additional supply permitted to enter about the bottom of the lampchimney.

in the usual way.

A'candle of this characteris particularly applicable to car-lamps, carriage-lamps, and the like, where the candle is fed upward as rapand also in about the bottom of a la1n.p-chim-' ney.

It is also apparent that in use the candle material might run through and into the tubular space, stopping up the air-passage. Ne propose, therefore, in instances where this is liable to occur, to employ a central metallic tube, 0, adapted to passifreely down through the tubular space in the candle. This metallic tube may form a part of the lamp in which the candle is to be burned. This will insure at all times the supply of air up through the center of the candle. Thetopof this-tube may be plain, or may be bell-shaped. Such a construction is shown in Fig. 5. In this same figure is also shown a candle in which the wick has tallow or candle material both upon its in side and outside, and with a tubular space at 7 the middle, either for the direct passage of air I V In testimony whereof we sign this specificaor for the passage of a metallic tube for coni tion in the presence of two witnesses.
